To all whom it may concern: .1 i 5 Be it known that I, JOHN PATRONELL, a citizen of the United States,1 residing at Orange, in the county of Orange and State of Texas, have invented new and useful Improvements in Safety-Cans, ofwhich the following is a specification.; a

The ob'ect of the invention is to provide a; can or similar receptacle withacover or closing means aglapted to be firmly locked in position to constitute a practically air-tight closure, while permitting the readyremoval of said cover when desired, without in any way detractin from the utility of. thecan or rendering the same unfit for subsequent use for theoriginal or any analogous purpose, and to this end the invention consists in the certain construction, combination and relation of parts hereinafter fully set forth, it being understood that changes in form, proportion and details may be resorted .to without departing from the spirit of the invention. i i 1 i l i In the drawing, y

Figure 1 is a side View partly broken a'wayof the receptacle having a cover constructed with a fastening device in accordance with the invention. 1 i

In theillustratedembodiment of in and providing respectively lower andupper shoulders, it being obvious that said? rings may be provided either by attachment to the inner surface of the receptacle or by heading the wall of the latter, as both methods are well known in the manufacture of receptacles of various types.

Removably fitted in the top of the receptacle and normally seated at its lower edge against the upper ring 11 is a sleeve 13 which is preferably tapered or reduced slightly toward its lower edge and is provided at its upper edge with an inturned flange 1e forming a stop for cooperation with an" cutturned. flan e 15 Which is formed an the hir at the rim it at? the ean Sept. 2, 1919.

'top or cover 17. The disk 18 which constitutes the closure supporting the flange 16 is of adiameter inexcess of the latter so as to a form albearing upon the upper. edge of the receptacle. as shown clearly in Fig.2.

Carried by the flange of the top or. cover 1 is a ring 19 with which are connected links 20 carrying shoes 21 of segmental form and adapted when folded to lie in close contact withthe surface of the flange, so that the top or cover with its flange and attached shoes may be withdrawn through theopening formed by thering 11 and raised until the flange 15 comes in contact with the flange or stop 14 on the sleeve 13 to avoid sepa ration ofsaid top or cover and sleeve. 1

when'thetop or cover is in its closed position the shoes 21 are interlocked with the rmg 12, and the adjacent surfaces of said shoes .ancl the shoulder formedby the ring 12 are serrated so that when the top or cover has been inserted and is turned slightly the engagement of the serrated surfaces will serve to hold the shoes against rotary movement .with the top or cover and will cause.

the links 120 to swing outwardto assume a position substantially radially of the top 'or prevented by shoulders or stops. 22 on the ring 19, a sufficient swinging movement however being permitted toconsti'tute an eccenltrio arc. In other words the rings are per- .mltted to swing under the turnlng movement in one direction in the turning of the top or cover: soas topass beyondthe center a suflicient distance to hold them in place and thus avoid the possibility of accidental disengagement and release of the top or cover.

On the other hand when it is desired to remove the cover 1t 18 only necessary to turn the same in the opposite direction from that above described in order to permit the links to swing in the reverse direction, sliding movement of the shoes being prevented by the interlocking motion of the same and the shoulder 12, whereupon the lid or cover may be elevated until its flange 15 comes in contact with the stop 1 1 on the sleeve 13. By a continued outward movement of the cover it will. understood that entire cover.

The depth of the flange 16. is such: that structure including the sleeve 18 may be removed fro-m the receptacle, thus exposing the interior of the can for the removal of its contents. The functlon of the tapering sleeve 13 is to form a guide for the downward movement'of the cover, so that said A cover will be seen in its downward movel to reduce evaporation of the contents of the can and entrance of dirt or dust thereto when the cover is partially withdrawn, as shown inFig. 3, and further cooperates with the disk 18 to seal the joint between the same and the upper edge of the can for the same purposeswhen the cover is fully applied, as shown in Figs. 1 and 2. r

scribed the opening of the can or receptacle can be accomplished "without mutilating either the body of the receptacle or the cover and when the latterhas been seated a slight turning anovement thereof, as to' the left,

will'insure a firm locking'of the same against further movement in the same directlon and 'the opening of the can except by the course above noted which consists in turning the lid 'or cover in the opposite direction so as to cause the release of the shoes or the disengagement thereof from the 1nter1or shoulders of the receptacle to allow the raising thereof.

Having thus fully described my invention, I claim 1. A receptacle having interior facing shoulders and a lid or cover havlng a depending flange or rim, shoes arrangedbe tween said shoulders, and links for connecting the shoes with the flange or rim of the lid or cover. l

2. The combination with a receptacle having an interior serrated shoulder, of a lid or'cover having a dependmg flange or rim, shoes-for arrangement 1n contact with said shoulder of the receptacle, and alink connection between the shoes and the flange or rnn of the 11d or cover.

. i 3. The combination with a receptacle proof the receptacle, links connecting said shoes with the flange 0r rim of the lid or cover, and means for limiting the swinging movement'of said links.

4. The combination of a can provided with interior spaced shoulders, of a lid or cover provided with an interior depending flange or rim,'shoes for arrangement in a plane between said shoulders of the can, adjacent surfaces of the shoes and one of the shouldersbeing serrated, links for connecting said shoes with the flange or rim of the lid or V V I cover, and means for limiting the swinging Obvlously with a construction such as de- 7 movement of said links in one direction.

5. The combination of a receptacle provided with interior spaced rings, a sleeve removably fitted within the receptacle and bearing upon the uppermost ring, a lid or cover having a flange or rim to fit within said'sleeve, shoes having a link connection with the flange or rim of the lid or cover and adapted to be arranged in a plane between the said rings of the receptacle, and

terior means for engagement with said flange of the sleeve, and shoes having link connection with the flange or rim of the lid or cover and adapted for arrangement in the space between said upper and lower rings of the receptacle and adapted to be spread by the turning movement of the lid or cover.

f In testimony whereof I affix my signature.

JOHN PATRONELL.
